ingrisa specification. h1s invention relates to an insect-killer V which 1s particularly adapted to destroy phyl-j loxerm and other vegetable parasites and to act at the same time as a manure winch fertilizesthe vegetable or plant to whieh 'itis applied. The invention is based on the novel discovery that the poisonous compounds of the oyanogen seriessueh as cyanid of potassium and the like-destroy hylloxerse and other injurious parasties "wifhin a comparatively short time, whereas they do not attaokthe vegetables or plants themselves. By adding to such compounds suitable nitrogenous norm" pounds-sueh as ammonia, sulfate of aminon, or other salts-a manure is obtained by" which the development of plants is greatly assisted. The addition of salts of ammonia also has the advantage that it assists the distribution of the poisonous cyanogen compounds, since the gas evolved the salts and satuenvelo ps the plants and permeates the soil surrounding the roots, and thus reaches each fiber and outlgrslg part. of the latter. Since the evolution of t disinfeotant gas is assistedby heat, it is desirable to add to the s nus en compounds and salts of ammonia a suite is proportion of quicklime, the latterheing'm that condition in ter.

which it is caused to crumble into dry 0wder by the addition of a small quantity 0 waammonia, and lime is moistened with a suffioient quantity of water, the absorption of the water is accompanied by the development of a considerable amount of heat. By this ,means the mixture is rendered very intmiate,

and the evolution of a s 7 gas in the manner desired is secured."

To reduce the cost of the disinfectant nia-i .nure and increase its efficiency, it is desirable to use'for its manufacture besides tassium cyanid residues from the distillation of illuoyani "weight pulverized residues of When the mixture of eyanid, salts of iron processhas been used for cleansing the gas. Sueh residues are, forinstance, ferricyanid of ammonium, cyanid of ammonium, and sulfocyanid of ammonium, and these substances are added to the mixture in a pulverizedlform'. It is also desirable to add to the mixture a deeol'oring agent-,-suoh as aluminium hydrosilieate, magnesium hydrosilieate; ohlorid of lime, hydrate of alumina, or the likeby which so-called lakes" are formed with the coloring-matter in the mixture, so that the said coloring-matter does not act on the plants. At the same time the fertilizing matter contained in the deoolorin agents is destructive to theanimal life of t e inseets and arasites on the plants.

T efollowin mixing proportions will serve to illustrate t e invention' by way of exampieiipulverized .quioklime, fifty-eight to sixty or sent, by weight; solid pulverized V of potassium, one-sixteenth per cent.,, by weight; ammonia or salts (pub verized) of ammonia; eight or sent, by

istillation 0bta'in od in the manufacture of coal-gas, sixteen to ei hteen per dent, by weight; solid pulverizef deooloring agents, sixteen to seventeen per cent, b Weight.

The residues of istillation obtained in the manofaoture of coal-gas when the iron process is used for purifying the gas have not always the same composition; but on the average the com osition may be stated in per cent, by weig t, approximately as follows:

As a deooloring a cut the following mixture can be used: 51' ica, 56.53 or cent, by weight; alumina or hydrate of a umina, 11.57

or cent.,byweight; magnesia, 6.29per cent,

Weight; water, 17.59 per cent, by weight; alkali, 1.28 per cent., by weight.

The constituents of the disinfectant manure are intimatel mixed while dry and fineler ulverized, whereupon they form a highly-e cient means for destroying phylloxerae and otherinsects and parasites of lants. Asuit able quantity thereof, amounting, for instance to five decagrams, but var ing according to the stage of the disease an the nature of the soil, can be inserted into a small conical recess in the earth surrounding the stem of the plant, the said recess being made by removing a portion of the said earth. The plant is then liberally watered, the stem being referably somewhat loosened before this is one b imparting to it a slight circular movement.

hen the water has been absorbed by the soil, the recess is filled up with earth, and it will be found that after the lapse of afew Weeks the leaves of the plant acquire a healthycolor of dark-green tint, the growth of the plant being powerfull stimulated and the parasites destroyed. he disinfectant manure can of course also be mixed with wa ter to form a paste or liquid mass, with which plants attacked by parasites are coated or s rayed. By this means also the complete estruction of the parasites is obtained.

The preparation can be applied to wineplants and to any other lants the development of which is interfere with b parasites. In the case of vines it is preferably a plied when the leaves are just appearing or s ortly before the plants are tied up. Other plants with strong stems can be treated in the same manner as vines. In the case of plants developed from seed the preparation can be sprinkled over the soil when the leaves appear, this being preferably done before or during the fall of rain.

An important advantage of the pre aration lies in the fact that the chemica s on which its action depends act in a nascent statethat is to say, during the reactions which take place when the reparation is applied. 'A partial effect of t e application can e observed after the lapse of from ten to fifteen days. The plant itself is not attacked by the preparation, and the flavor of tnc fruit is not affected. The growth and development of the plant are, in fact, as already explained, assisted at the same time as the disease is removed.

Having now fully described our invention, we declare that what we elaim is- 1. An insecticide consisting of a soluble oison of the cyanogen series to which quick lime is added t e mixture serving, when acted upon by water, to evolve a poisonous-bearing aqueous vapor.

2. A combined insecticide and manure consisting of a soluble oison of the cyanogen series to which quicklime and nitrogenous compounds are added the mixture serving, when acted upon by water, to evolve a poison ous-bearing aqueous va or.
